I just received God of War 3 and just want to be able to download the skins on Thursday no matter how long it takes. I live on a university campus that has free internet access but 1. the school doesn't allow students to connect to the internet through consoles 2.I tried anyway but the security settings for the school's internet provider is "not supported".

If I could do that, then I wouldn't have bothered asking the question!

Also, I have an ethernet cable. Is that the only thing I need or would I still have to install the software you mentioned.
